My invention relates to safety razors, and its primary purpose is toprovide a safety razor frame adapted for using a single safety razorblade over relatively long periods of time by providing means associatedwith the frame for securely holding the blade in position forconditioning, as by stropping and/or honing.

A further object of my invention consists in so constructing the safetyrazor frame that it may be encompassed within small space and that itmay be used over relatively long periods with practical freedom frommechanical and operating annoyances.

A still further object of my invention consists in providing a supportfor the razor blade that may be precisely adjusted to meet the operatingrequirements of the user.

My invention comprises a primary handle member having a sleevethreadably disposed about the central outer surface thereof. A safetyshaving head adapted for holding a razor blade in position for shavingis disposed upon one end of the handle member, and a clamping headadapted for holdinga razor blade in position for conditioning isdisposed upon the opposite end of the handle member.

With these and incidental objects in view, the invention consists incertain novel features of construction and combination of parts, theessential elements of which are set forth in the appended claims, and apreferred form of embodiment of which is hereinaftershown with referenceto the drawings which accompany and form a part of this specification.

In the drawings:

Like reference characters refer to like parts throughout the followingviews.

My device is comprised primarily of a handle member 11, one end of whichis bifurcated at 2, resulting in a top member 3 and a bottom memberdisposed in parallel. A clamping head 5 is disposed longitudinally ofthe primary handle member. A guard B terminates the head end of thebottom member l. A toothed comblike structure 1 terminates the workingedge of the guard 6. An outer face 8 of thetop member 3 and outer face'9 of the guard 6 lie in a common plane. The clamp 5 is expanded at itsouter end and terminates inclamping jaws it and it that are adapted toencompass the ends of a razor blade l l. 'Notches l2 and it are disposedin theopposite ends of the razor blade 14. These notches are preferablyplaced near the top edge of the blade and in registry alignment witheach other. These notches serve as indexing means for precisely locatingthe razor blade in place.

Clamp 5 has a stem l5 extending inwardly along the axial center line ofthe primary handle member. The clamping head is extended to form afan-like head as illustrated at I6 and an elongated slot I7 is disposedtherein, through which adjusting screw l8 passes. The head end of theadjusting screw I8 is a free fit in hole Iii which is disposed withinthe top member 3. The adjusting screw 58 is threaded into the bottommember 4. The handle member is preferably made of spring material inorder that the outer ends of the bifurcated handle member may be movedtoward each other against spring tension. Rotation of the adjustingscrew causes a relative displacement between the top and lower membersof the bifurcated handle member, and consequently causes relativedisplacement between the cutting edge 22 of the razor blade and theouter ends of the guard teeth '5. Lugs 26 and 2! extend forwardly fromthe outer ends of the top member 3 and are made to engage with notchesl2 and 13 disposed in the ends of the razor blade. The stem i5 isthreadably secured to a finger adjusting nut 23 having a sleeve 2 tfixed thereto. A relatively long threaded connection is provided betweenthe sleeve 24 and the stem Hi to provide for adequate travel of theclamping head 5 to freely release the razor blade when its removal fromthe safety shaving head is desired. I A stropping clamp 25 is slidablydisposed relative to the primary handle member. A reverse bend 26terminates the outer end of the stropping clamp. A lug 21 is disposedupon the elongated inner end of the stropping clamp. A friction sleeve28 is disposed about the primary handle member l, and the stroppingclamp extends therethrough. V-shaped notches 29 and 30 are disposedadjacent the back of the razor blade Hi. Wedge shaped jaws 3i and 32 aredisposed respectively within stropping clamp 25 and on the c sleeve 28and are held in registry alignment with each other, and are adapted forengaging within the V-shaped notches 29 and 30 of the razor blade, tohold the blade in fixed position for honing and/or stropping.

To place the razor blade Within the conditioning head of the razorframe, clamp 25 is moved outwardly to receive the blade between theclamping jaws, in which position the lug 21 engages with a shoulder 33,limiting the outward movement of the clamp 25. A band 34, thread-' ablysecured to the primary handle member I, is made to abut the sleeve 28.When the razor blade has been placed within the clamping jaws 3i and 32a tight clamping pressure is provided upon the blade by the longitudinalmovement of a band 34 against the sleeve 28, said longitudinal movementbeing effected by the rotation of the threaded band 34 upon the primaryhandle member I. This places the razor blade under compression betweenthe jaws of the conditioning head.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the embodimentherein shown and described, as it is susceptible of embodiment invarious forms, all coming within the scope of the claims which follow.

What I claim is:

1. In a device of the class described, the combination of a safety razorblade having a substantially thick back, a pair of rectangularlysectioned notches disposed in the ends thereof, a pair of notches havinga V-shaped section normal to the blade thickness disposed in the endsthereof between the said rectangularly sectioned notches and the saidback, a safety razor frame member having two ends and adapted at one endfor holding the safety razor blade in position for shaving and adaptedat the other end for holding the safety razor blade in position forconditioning the same.

2. A razor blade, comprised of a one piece member, the said blade beingthicker at its back than at any other point, a slot disposed within theoppositely disposed ends of the blade and in registry alignment witheach other and that point of the blade ends disposed above the slotsbeing V-shaped and the apex of the V being inwardly disposed from theouter edges of the blade ends.

3. In a device of the class described, the combination of handle member,a stropping clamp disposed longitudinally of .the handle member andoutwardly extending therefrom, a reverse bend disposed Within the outerend of the stropping clamp, J-shaped jaws disposed in the outer end ofthe handle member and in the outer end of a friction sleeve, anddisposed in registry alignment with each other, a lug disposed upon theinner end of the stropping clamp, said lug being adapted for engagingupon a shoulder of the handle member when extended to limit the outwardmovement of the stropping clamp, a friction sleeve disposed upon theouter end of the handle member, and a band threadably secured to thehandle member and adapted for engaging the friction sleeve and formoving the same outwardly longitudinally of the handle member.
